APPENDIX G - Communications
The command set used to communicate with the DV-III is as follows:
COMMAND COMMAND RESPONSE
Name from Computer from DV-III
k(Reset) <K><CR> No Response
E(nable) <E><CR> <E><ss><CR>
R(etrieve) <R><CR> <R><vvvv><tttt><ss><CR>
V(elocity) <V><xxxx><CR> <V><ss><CR>
I(dentify) <I><CR> <I><ddd><mm><CR>
Z(ero) <Z><CR> <Z><vvvv><ss><CR>
Illegal String <????><CR> <ss><CR>
Where:
vvvv = Transducer reading as 4 hex digits. The Rheometer calibration should yield a reading of
approximately 0400H when zeroing or at rest, and a reading of approximately 2B00H at
100% torque.
tttt = Temperature reading as 4 hex digits. The temperature circuit is normally calibrated to
produce a reading of 2700H at 0 (zero) degrees Centigrade with a linear scale of 40 counts
per degree C.
xxxx = Stepper motor speed as 4 hex digits. The motor speed command from the Host is in RPM
with an accuracy of 0.1 RPM. Thus, 0064H (100D) would equal 10.0 RPM. (Note: RPM
in decimal notation must be multiplied by 10 when converting to hex.)
ss = Status Byte as 2 hex digits.
ddd = The ASCII characters “DV3”.
mm = These 2 characters will be used to represent the model for which the DV-III is configured.
The model decoding is shown in Table G1 below.
